    "description": "Catalytic converter theft entered the public consciousness sharply around 2021--2022, when surge coverage made it feel ubiquitous in many metro areas. By 2024 the perceived risk had tempered somewhat as laws tightened and insurance claims data showed a steep decline from peak years. No rigorous national survey measures worry about this specific crime separately from general vehicle theft.\n",

    "assumptions": "NICB reports approximately 14,000 catalytic converter thefts (insurance claims) in 2024, down from a peak of ~64,700 in 2022. There are roughly 140 million vehicle- owning households in the US. Annual probability per vehicle-owning household at 2024 rate: 14,000 / 140,000,000 = 0.0001 per year. Over 59 adult years at this rate: 1 − (1 − 0.0001)^59 ≈ 0.0059. However, the 2019--2024 period averaged roughly ~40,000 claims/year across the surge cycle; using a 10-year rolling average of ~30,000/year: 30,000 / 140,000,000 = 0.000214/year → 59 years = 0.012. Uncertainty is wide because NICB insurance claims undercount total thefts (many are not insured or reported); actual theft incidents may be 2--4x the claims figure. The 0.012 figure represents a mid-cycle average. The 2024 rate would yield ~0.006 lifetime; the 2022 peak rate would yield ~0.027.\n",

Independent estimates suggest actual theft incidents may be 2--4x the claims count. The sharp rise and subsequent fall in thefts (peak 2022, 68% decline by 2024) reflects a crime wave driven by precious-metal prices and suppressed by state legislation requiring vehicle title documentation for scrap metal sales. Future rates are uncertain; precious- metal prices and legislative enforcement effectiveness will shape the trend. The lifetime figure assumes continuation of a 10-year average rate rather than the anomalous 2022 peak. Only vehicle-owning households face this risk, excluding roughly 10% of US households without a registered vehicle.\n",
